@jip That sounds great, how do I go by doing that? I have FA and the FAF client installed.
Edit: @Photek filled me in on how to do that, for anyone else who might be interested:
To play FA campaign via FAF
1- open the client
2- open play tab
3- open co-op tab
4- pick appropriate campaign mission
5- Optional - Set password to make your game private
6- set title
7- Host your game 🙂

@thecore Yeah I do have XMP turned on, nothing else though.

@ZLO The stutter in the video is independent of mouse movement or zoom level. I'm flicking the mouse around to show that it's not the recording that's stuck but the game. No spikes in CPU or GPU temp/utilization.
I tested running a skirmish map and spawning as many units as I could and I got to 400+ units with no issue whatsoever. I don't know what to say really lol.
Continued playing the campaign with no issue though.
